AISI Publishes Design Flowchart for Using the North American Specification and AISI Cold-Formed Steel Design Manual

WASHINGTON, D.C., Sept. 25, 2009  – The American Iron and Steel Institute (AISI) announced today the publication of a Design Flowchart for using the 2007 Edition of the North American Specification and the 2008 Edition of the AISI Cold-Formed Steel Design Manual. The document is available to download free of charge at

This design tool provides an overview of the North American Specification and the AISI Cold-Formed Steel Design Manual, outlines the overall consideration of cold-formed steel design, and draws correlations between the Specification design provisions and the corresponding design tables, charts and examples provided in the design manual. It consists of 22 pages.

Jay Larson, P.E., F. ASCE, managing director, construction technical for AISI, said: “The AISI Cold-Formed Steel Design Manual provides useful supplemental materials to AISI S100, the North American Specification. This new design flowchart will help users find examples in the design manual that illustrate the design provisions in the North American Specification. It will also help them use the tables and charts that implement the corresponding design provisions. An added benefit is that the flowchart outlines the steps that a design engineer needs to consider when designing with cold-formed steel members.”

AISI’s codes and standards work is conducted under the Construction Market Council of AISI’s Steel Market Development Institute (SMDI). The SMDI oversees the industry’s investment in advancing the case for steel in the marketplace as the preferred material of choice. AISI serves as the voice of the North American steel industry in the public policy arena and plays a lead role in the development and application of new steels and steelmaking technology. AISI is comprised of 24 member companies, including integrated and electric furnace steelmakers, and 138 associate and affiliate members who are suppliers to or customers of the steel industry. AISI’s member companies represent over 75 percent of both U.S. and North American steel capacity. For more news about steel and its applications, visit
